[The effect of temperature changes on evoked potentials of the fish olfactory bulb].

Perches were kept at 10 degrees C and fixed in a chamber through which water was perfused. During the experiment the water temperature was changed. The potentials induced by electric stimulation of the olfactory nerve were recorded from the dorsal surface of the olfactory bulb. The oscillations of the evoked potentials separated into several components when the temperature was lowered. Six components were found in the evoked response of the olfactory bulb at 8 degrees C.
